Hey Metal god, your quote: http://www.amazon.com/UTG-DS3840-4-I...I2GEFS5W408V4U This is the Red-Dot on the black AR . I bought and use this on my 10/22 primarily. I have used it on the AR and it seemed to work fine . I say that cus one time it lost zero . At the time I did not have the windage & elevation knobs locked down so that might have been why .

Metal god, 1) Were you using the rifle when the scope lost zero, or did you remove it off the rifle?

2) How did you regain the zero?

3) Has this red dot scope held zero since then?

4) I'm now considering getting this red dot. I think a red dot would better suit my older eyesight. I'm assuming that it is parallax free?

5) I also assume that this red dot holds up to the mild recoil of the 5.56/.223?
